10+ Automobile Technician Interview Questions and Answers

An engine is a machine that converts fuel into mechanical energy. There are several types of engines used in automobiles.

• An engine is the power source of a vehicle, responsible for generating the necessary energy to propel the vehicle forward.

• The most common type of engine used in automobiles is the internal combustion engine, which burns fuel within the engine to produce power.

• Internal combustion engines can be further classified into two types: gasoline engines and diesel e...read more

The firing order of a four piston engine is the sequence in which the spark plugs ignite the fuel-air mixture in each cylinder.

• The firing order is determined by the engine design and is usually specified in the vehicle's service manual.

• It is important to follow the correct firing order to ensure proper engine performance and avoid damage.

• For a four-cylinder engine, the firing order can vary depending on the engine configuration. Some common firing orders are 1-3-4-2, 1-2-4-3,...read more

Regular maintenance, proper driving habits, and timely repairs can help keep a car in good condition.

• Follow the manufacturer's recommended maintenance schedule

• Check and change the oil regularly

• Inspect and replace air filters

• Keep tires properly inflated and aligned

• Avoid aggressive driving and excessive idling

• Address any issues or warning signs promptly

• Store the car in a covered and protected area

• Clean both the interior and exterior regularly

The engine is the main power source of an automobile. It can be of various types such as gasoline, diesel, electric, or hybrid.

• The engine converts fuel into mechanical energy to power the vehicle.

• Gasoline engines use spark plugs to ignite the fuel-air mixture, while diesel engines use compression ignition.

• Electric engines use electricity stored in batteries to power the vehicle.

• Hybrid engines combine both gasoline/diesel and electric engines for improved fuel efficiency.

• Examp...read more

The frequency of car services depends on various factors such as mileage, age, and maintenance history.

• Car manufacturers generally recommend servicing every 6,000 to 10,000 miles or every 6 to 12 months, whichever comes first.

• Regular maintenance tasks include oil changes, filter replacements, tire rotations, and fluid checks.

• Older cars or those with high mileage may require more frequent servicing to ensure optimal performance and prevent breakdowns.

• The service schedule may a...read more

The engine was discovered in the late 19th century.

• The first practical internal combustion engine was developed by Nikolaus Otto in 1876.

• However, the concept of engines dates back to ancient times with the invention of steam engines.

• The development of the modern engine involved contributions from various inventors and engineers.

• The engine has undergone significant advancements and improvements over the years.

The engine works by converting fuel into mechanical energy through a series of combustion processes.

• The engine operates on the principle of internal combustion, where fuel is ignited inside the engine cylinders.

• Fuel and air mixture is drawn into the cylinders through intake valves.

• The mixture is compressed by the piston, increasing its temperature and pressure.

• A spark plug ignites the compressed mixture, causing a controlled explosion.

• The explosion forces the piston down, con...read more

CTC stands for Current Cost to Company and CTV stands for Expected Cost to Company.

• CTC refers to the total salary package of an employee, including all benefits and allowances.

• It includes the basic salary, incentives, bonuses, and other perks provided by the company.

• CTV is the expected salary package that an employee is looking for in a new job.

• It is the amount the candidate expects to earn in terms of salary and benefits.

• The CTV may vary based on factors like experience, ski...read more

There are two types of stroke engines: two-stroke and four-stroke.

• Two-stroke engines complete a power cycle in two strokes of the piston: compression and combustion/exhaust.

• Four-stroke engines complete a power cycle in four strokes of the piston: intake, compression, combustion, and exhaust.

• Examples of two-stroke engines include chainsaws and motorcycles, while examples of four-stroke engines include cars and trucks.

Regular maintenance includes checking and replacing fluids, inspecting belts and hoses, changing filters, and performing tune-ups.

• Check and replace engine oil and filter every 3,000-5,000 miles.

• Inspect and replace air filter every 12,000-15,000 miles.

• Check and replace spark plugs every 30,000-100,000 miles.

• Inspect and replace timing belt every 60,000-100,000 miles.

• Check and replace brake fluid every 20,000-45,000 miles.

An engine is a machine that converts fuel into mechanical energy to power a vehicle.

• An engine is the heart of a vehicle, responsible for generating power.

• It converts fuel (such as gasoline or diesel) into mechanical energy.

• Engines come in different types, such as gasoline engines, diesel engines, and electric motors.

• They typically consist of various components like cylinders, pistons, valves, and a crankshaft.

• Examples of engines include V8 engines, inline-four engines, and el...read more
